Voestalpine

Voestalpine Camtec GmbH is a renowned international supplier of maintenance-free, self-lubricating sliding elements, whose products are mainly used in automotive stamping dies, tools and machines for plastics processing, as well as in other industries. Cam units we offer are extremely versatile and can be used in punching, shearing and sheet metal shaping processes. Close cooperation with our clients has helped us develop an innovative generation of cam units that meet all their requirements. Our cam units are characterized by a compact design, which makes them extremely practical in installation and use. Additionally, they are designed to carry very heavy loads, ensuring reliability and durability in a variety of applications. Our goal is to provide solutions that contribute to the optimization of production processes and increased operational efficiency of our clients.

Advantages of cam units:

  • optimum fit thanks to maintenance-free sliding elements
  • hardened and ground surfaces
  • long service life due to minimal wear and abrasion
  • precise guidance
  • high absorption of lateral forces
  • adjustable clearance
  • adjustable and removable gas spring
  • all components available as spare parts
  • compliance with the NAAMS standard
  • patented drive system

O-KS - optimized, new generation compact cam units

Forming, flanging, piercing, trimming — cam sizes and force requirements are important and critical factors in the stamping process. As a solution voestalpine Camtec developed a new cam generation which brings us to the next level. The result is the O-KS (optimized compact cam unit). Our latest achievement will prove its superiority with its compact but simple design, easy handling and high retraction forces.

O-BS - optimized, new generation basic cam units

Our newly developed basic cam is an economical alternative to our premium series. With a load-dependent service life of up to one million strokes, it impresses with its optimized application options, simplified handling and strong forces. Like all voestalpine Camtec cam units, our optimized basic cam is well designed and consists of only a few components. This significantly simplifies spare parts management and the exchange of individual parts. The side plates with double prism enables maximum precision in the smallest installation space. The side plates can even be easily readjusted in the press. The O-BS can be removed to the rear and to the side, thus ensuring efficient use in the tool and extremely simple maintenance.

Dimensions

  • Work surface: 60 – 500 mm*
  • Angle: 0 – 75° (5° step)

Technical properties

  • Average service life: 1 million strokes
  • Guaranteed service life: 500 000 / 750 000 strokes
  • Delivered in assembled condition
  • Sinter side plates
  • Complies with BAK, VDI
  • NAAMs insertion point
  • Special cam unit options
  • At least 600 N/mm² driver tensile strength, sliding element and cam bed materials

O-ES - optimized, new generation elemantary cam units

The new O-ES cam unit series is based on the proven voestalpine design. Double prism drive plus side plates that were designed for price-sensitive industries and clients. As usual, O-ES is equipped with strong gas springs to provide you with high retraction forces. Fewer parts mean less complexity without impacting service life.

Dimensions

  • Work surface: 50 – 500 mm
  • Angle: 0 – 75° (5° step)

Technical properties

  • Average service life: 1 million strokes
  • Guaranteed service life: 300 000 strokes
  • Casting material min. EN-GJS-400-15
  • Retracting force similar to O-KS series
  • Working force approx. 30% of O-KS
  • Driver lock
  • Can be removed to the rear
  • Simple processing possible
